RE: How To Have A Friend Before 8 AM Tomorrow?

Just like I'd written for Part 1 (if we can call it that 😂), I'm sorry you're going through this.
Like you've written here

I believe that friendships are the same as romantic relationships

You're right. Because the betrayal from either stings just as badly. What particularly helped me cope when I had to cut off some girls who were my best friends was:

1. Having this "good riddance" mentality. Like you, after my friendship with those girls ended, I had to self-check. Like, am I really the problem? Because before them, I'd lost some other "female" friendships as well. Through this analysis, I realized that our values didn't align, and that's why the universe kept removing me from friendships (with or without my consent) that don't align with the woman I hope to be. Now, just to give a background context, these girls gossip about people and even one another a lot. Doesn't that just sound like good riddance?

2. Music became my companion. I was ALWAYS on headset. And as much as that might make you seem like a loner, it really doesn't matter. It's your world, and you're the main character in it. Who cares what someone else's perception of you is? Someone who, by the way, has not lived a second of your life. So yeah, if music can become a coping mechanism, tune in.

3. Make other friends but not for "bestie" purposes. One of the things I've realized about life is that we humans always try to control the outcome of a situation, that's generic by the way, not specific to you. Rather than zoning heavily on, "I'm new here, I don't have other friends".......I think you can shift the focus to "what's meant for me will find me". And as much as that sounds like some motivational affirmational shebang, lol, it works for a mindset shift. Be comfortable in YOUR own company. Even if you're alone, do things that are fun for you, e.g., playing games on your phone, reading, etc. Be kind and SMILE at people. From there, someone might see a book you're reading and just start a conversation with you.

Oh yeah, one more thing, the best way to start a conversation as a new person is by asking a question.

But most importantly, just ease into the moment, allow life to teach you whatever lesson it's trying to pass across from this situation, and trust it to bring the good friendships you need to you eventually. As for those, it's their loss, not yours.

Have a fun day!
